Classification of Plants
Plants are classified into groups like algae, mosses, ferns, and flowering plants, based on features like reproduction and structure.
Core concept
Algae are simple plants, mostly found in water, that don't have true roots, stems, or leaves.
How it works
Mosses are small, simple plants without a vascular system, often growing in moist, shaded areas.
Why it matters
Ferns have vascular tissue (like xylem and phloem) but reproduce using spores rather than seeds.
Key detail
Flowering plants (angiosperms) are the most diverse group, reproducing through seeds contained within flowers and fruits.
